SPECIFICATION forming part of Letters Patent No 293,675, dated February 19, 1884.

I Application filed September .20, 1883. (No model.)

To all whom it 11mg concern:

Be it known that I, FREDRIGK P. ROSBAOK,

of Chicago, Illinois, have invented certain new 7 and useful Improvements in Metal-Planers, of which the following is a specification.

The invention consists in improvements in devices for reciprocating the planer-bed stead ily and uniformly, without the usual shock and jar which results from the use of gear-wheels and the many devices now in common use, and

My invention consistsin attaching directly to the outer end of this screw the powerpulleys, and making the said pulleys revolve in the direction desired, to secure the twoway or reverse movement thereof by means of a double friction-clutch that will alternately clasp and release the pulleys, to give the requisite' reverse revolution to the screw thatv causes the planer-bed to travel back and forth on its ways or track; and it consists in devices constructed and operatedsubstantially as hereinafter described, and shown in the drawings.

Figure 1 is a side elevation view of a planer embodying my invention. Fig. 2 is a top or plan view of the same. Fig. '3 is a longitudinal section. Fig. 4 is a section on line f f of Fig. 1. Fig. 1 5 is a detail view of sliding sleeve and its manner of attachment. Fig. 6 is a detail view of the wedged-shaped yielding stop-pin. Fig. 7 is a detailed section, showing construction of pulleys and the clutching-- disk and the manner of operation. Fig. 8 is rial is placed to be planed, and which ismoved back and forth under the cutter by the screw F.

G O are the pulleys revolving the'screw.

D is the sleeve, secured by means of a key or pin, D, passing through aslot, F, in the screw, which admits of an endwise adjustment of the clutch-sleeve in the slot F, and to which the sliding bar or shaft G, that carries the friction-disk C, .is secured.

E is a roller of bevel form, placedone on each side of the shifting-lever f, and fitting the surface thereof closely. I

F'isthe screw that imparts motion to the traversing carriage or table B.

G is the bar or shaft that connects the sleeve D to the friction-disk G.

h h arepins or lugs fitted loosely in the disk 0, for the purpose of holding the operatingpulleys O O apart. Said pulleys revolve loosely on the screw-shaft when disconnected from the friction-disk O. The friction-disk C is fitted loosely on the screw-shaft, and is connected thereto by a pin or key, 0, which slides in the slotted hole G in the screw-shaft F. Said pin or key is firmly secured in the.

shaft G, which carries or revolves the frictiondisk 0, the slot G admitting of the sliding of the disk or clutch shaft to and from the pulleys alternately, as required.

G is a cap retainingthe pulley O on its shaft.

t i indicate a space between the pulley and its clutching-disk, which serves as an air cushion to prevent any shock or jar when the disk shall engage with the pulley. V

a a are projecting or trip lugs secured to the 'side of the reciprocating table B.

b is a tripping arm or lever secured firmly to the rock-shaft c, which rock-shaft has its support on the mainframe.

d is a rocking crank secured firmly to the shaft 0, and connected to rod e, which is connected to the shifting-lever f, said lever f be ing supported by a pin, f, secured to the main' frame, which serves as its fulcrum, and upon which it vibrates, it being retained on either side by a wedged-shaped pin, 9, which pin has a vertical movement in its supporting-arm g, which is secured to the main frame, and rests upon a coiled spring, adj ustably secured by a set-screw, g.

D is a collar firmly secured to the stem or shaft F, to retain said screw firmly in the main frame A.

I claim as my invention 1. In a metal-planing machine, the combination of a reciprocating table, B, the screw F, with its actuating-shaft G, disk 0, and pulleys O O, substantially as shown and described.

2. The combination of the carriage B, screw F, its actuating-shaft G, disk 0', and pulleys C 0, provided with space i i, said space serving as an air cushion to'the sliding disk 0', pulleys C O, and carriage B in its operation, substantially as shown and described.

3. The combination of the screw F, provided with slots F G, shaft G,with its pins or keys D 0, disk C, and pulleys G U, with the sliding carriage and the tripping devices, substantially as shown and described.

4. The planer-carriage B, provided with lugs a a, screw F, shaft G, clutch O, pulleys O 0, pins or keys D C, clutclrsleeve D, rockshaft 0, and crank-levers b d, rod 0, and clutch lever f, to impart reciprocating movements to said carriage, substantially as shown and described.

5. The sliding carriage B, provided with the lugs to a, the rock-shaft 0, its crank-levers I) (1, rod 0, cluteh-leverf, stop-pin g, clutchsleeve D, and rollers E Eand shaft G, for imparting reciprocating movements to disk 0, in combination with the pulleys O C and the screw F, whereby the planer-bed is caused to move back and forth.

6. The pulleys C C and their belts traveling in opposite directions, the friction-disk 0, its sliding pins 7i h, reciprocating shaft G, and its pin G, for imparting rotary movement to shaft F, substantially as shown and described.

7. The shiftingdever f, its fulcrum f,bevelwheels E E, sleeve D, vertical sliding stoppin 9, provided with its spring g, and setscrew r/ and supporting-ar1n r/, substantially as and for the purpose set forth.

8. In the mechanism imparting a reciproeating movement to a planer, the screw F, the friction-disk C, and the pins h h, fitted loosely therein and projecting beyond the sides therei of, in combination with the pulleys O C, whereby a space is secured for compression of air, which serves as a cushion, preventing sudden shock or jar in the shifting of said frictiondisk, substantially as shown and described.

9. The reciprocating fri'ctionclutch C, provided with its two bevel-edges, for alternately engaging pulleys C O, and its sliding pins hh,

shaft G, and screw F, substantially as shown, and for the purpose described.
